Answer 1

Answer:

The given system of inequalities is expressed as

$\begin{gathered} 24x\text{ + 8y }\ge\text{ 20} \n 3x\text{ - 6y > 24} \end{gathered}$

The first step is to change the inequality symbols to that of 'equal to" and plot the straight line graph for each equation.

For the first equation, the line on the graph would be solid because the symbol is "greater than or equal to"

For the second equation, the line would be broken because the inequality symbol does not have an "=" symbol

The graph is shown below

Jessie owns a hot dog stand and sells specialized hot dogs. He charges $1.50 for a plain hot dog and then an additional $0.50 for each topping that you want. This can be modeled by the equation C = .5x + 1.5, where C is the total cost of the hot dog and x is the number of toppings you ordered. The company that he buys his hot dogs from was having a sale so he was able to buy the hot dogs for less. He will now sell them for $0.25 less than before. What should be changed in the equation C = .5x + 1.5 to represent this?

Sleeping in college. A recent article in a college newspaper stated that college students get an average of 5.5 hrs of sleep each night. A student who was skeptical about this value decided to conduct a survey by randomly sampling 25 students. On average, the sampled students slept 6.25 hours per night. Identify which value represents the sample mean and which value represents the claimed population mean.

Answers

Answer:

Sample mean = 6.25 hours per night.

Population mean = 5.5 hrs of sleep each night.

Step-by-step explanation:

A sample mean is the mean of the sample collected. The 25 students surveyed by the student is the sample. The average sleep time derived from the sample is the sample mean.

A population mean is the mean of all the population. Here the population are college students. The population mean is the mean derived from studying the sleep duration of all the population - college students

2) On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled in miles, d, to the number of hours flying, t, is t= d. How long will it take the airplane to travel 800 miles? Show your work 500

Answers

The equation for relation of time with distance travelled is,

$t=(1)/(500)d$

Substitute 800 for d in the equation to determine the time required for travelling 800 miles.

$\begin{gathered} t=(1)/(500)\cdot800 \n =(8)/(5) \n =1.6 \end{gathered}$

So airplane take 1.6 hours to travell 800 miles.

Answer: 1.6 hrs
